JSPM like package management?

I’m not sure where the right place to put a feature request is, but it’d be great if we could get JSPM style multi-source package management. I’ve used that a couple of non-meteor projects, and it’s the beesknees. You can add packages from npm, github, or even bower, and it figures out how to tie it all together.

It’d be great if Meteor made package management that easy.
